FULL PROBLEM DESCRIPTION
------------------------            
1) MPEG1 System streams with lots of padding at the top will
fail to parse/load.  Vsparse is not looking far enough into the
stream to find the Video Sequence Header.
2) Some low bitrate MPEG1 System streams will not play correctly -
the VideoCharger player will report an Active Movie error
return code.
3) Some MPEG1 audio-only streams will not play correctly -
the VideoCharger player will report an Active Movie error
return code.  This depends on the level of the Windows Media
Player that is installed on the client system.

For #2 & #3, rerunning vsparse on the assets will allow them
to be played/streamed correctly.  Here is a Korn shell script
that will reparse ALL assets on a VideoCharger server:
   for asset in $(vslist) ; do
      vsparse -a $asset
   done


FILESETS:   avs.com.rte 2.0.0.4

SUPERSEDED PTFS:
----------------
IY00607 Quicktime4 media support

Support for Quicktime media type

IX88051 MPEG2 stream (encoded by NORTEL) will not parse.

vsparse fails with error: 0xffffffff when parsing
MPEG2 program stream files where the system header
stream id table contains 0xb8 and 0xb9 entries to
refer to all audio and video streams, and doesn't
contain 0xc0 and 0xe0 entries for specific streams.

IX87604 Some MPEG1 Audio-only streams show incorrect bitrate/duration.

Layer 1 and Layer 3 MPEG1 Audio-only assets show incorrect bitrate
and duration when using vslist -a <asset>.  Layer 2 streams are correct.

INSTALLATION INSTRUCTIONS 
--------------------------
(1) Download the file "avs.com_2.0.0.4.bff"
in binary mode into an empty directory on your VideoCharger server.

(2) Logon as user 'root'.  Stop the VideoCharger Server by
using the command "stopsrc -cg vs".  Type the command 
"lssrc -g vs" to verify that all the processes have stopped.

(3)Apply the update using the command "smitty update_all".
For "INPUT device / directory for software" specify the 
directory in which you saved the .bff file.
        
(4) On the "Update Currently Installed Software to Latest Level" panel,
press the 'enter' key to start the installation program.    

(5) After installation has completed successfully restart the VideoCharger
server by using the command "startsrc -g vs" at the command prompt.
